Next from Apple: A pedometer that never misses steps?

Documents released Thursday at the U.S. Patent and Trademark Office show that the company is working on a device to more accurately measure a person's movement—presumably for a health-monitoring wearable device.

Tech Yeah! iWatch coming?

Alex Gauna of JMP Securities expects Apple to take the iWatch mainstream and expects it to reach the public by Fall, 2014.

The patent covers a "smart wrist-mounted pedometer that can automatically determine its location on a user's body and compensate for missed steps using advanced processing algorithms," according to Apple Insider.

The company first filed a series of patents related to pedometer accuracy in April 2013.

Analysts are looking for the tech giant--whose stock is down slightly from the beginning of the year--to introduce new product categories to excite buyers again.
